ADM2484EBRWZ-REEL7

Overview

The ADM2484EBRWZ-REEL7 is an isolated RS-485 transceiver from Analog Devices, utilizing iCoupler technology for galvanic isolation. It supports data rates up to 500 kbps in half-duplex or full-duplex modes. The device integrates a DC-DC converter and provides ±15 kV ESD protection on the bus pins. It operates within a supply voltage range of 3 V to 5.5 V and functions at temperatures between -40°C and +85°C. Packaged in a 16-pin SOIC with a 2500 Vrms isolation rating.

Feature Summary

• Integrated DC-DC converter eliminates external isolation power requirements
• iCoupler magnetic isolation technology ensures high reliability without optocoupler constraints
• Robust ±15 kV electrostatic discharge protection on the differential bus lines

Applications

• Industrial process control systems
• Building automation and lighting controls
• Metering infrastructure
• Battery charging systems

Procurement Notes

Verify the specific suffix REEL7 corresponds to the reel packaging configuration required for your assembly line. Confirm that the 500 kbps data rate specification aligns with your system's communication speed requirements. Ensure the 16-pin SOIC footprint matches your PCB layout design before finalizing procurement orders.

Selection Notes

Select this component when designing isolated RS-485 networks requiring integrated power conversion. It is suitable for applications needing robust ESD protection and compact form factors. Consider the 500 kbps throughput limit against higher-speed alternatives if faster communication is necessary. Verify compatibility with existing microcontroller logic levels.
